FAQ
After sales service plan for Roots blower
I,Service Commitment
1. Quick response mechanism
Provide a 7 × 24-hour service hotline, respond within 2 hours after fault repair, and arrange for technical personnel to arrive on site within 48 hours.
Prioritize handling emergency faults that affect production and minimize downtime losses.
2. Original parts guarantee
All replacement parts are produced by the original factory to ensure compatibility and performance matching with the equipment.
Adequate reserve of commonly used accessories, supporting emergency delivery (such as impellers, bearings, seals, etc.).
3. Professional team support
The engineering team has over 10 years of maintenance experience and is familiar with various fault diagnosis techniques, such as abnormal noise, insufficient air flow, and high temperature alarms.
Provide maintenance qualification certification and technical training records to ensure professional service.
II,Service Content
1. Service during the warranty period
The entire machine comes with a one-year free warranty (excluding vulnerable parts such as belts, filters, etc.), with no labor or accessory fees during the warranty period.
Provide free equipment inspection once a month to detect key parameters such as vibration, temperature, and current.
2. Parts replacement and repair
Support core maintenance projects such as impeller dynamic balance calibration (accuracy ≤ 0.05mm) and gear clearance adjustment (standard 0.10-0.18mm).
Provide optimization solutions for high-frequency issues such as bearing wear and seal leakage, such as upgrading the dual lip fluororubber oil seal.
3. Technical training and guidance
Free operation training (including equipment start stop, daily inspection, and basic troubleshooting) is provided.
Distribute the Maintenance Manual, which includes lubrication intervals (such as changing bearing grease every 2000 hours), belt tension adjustment methods, etc.
III, Service Process
1. Fault declaration
Users can submit fault descriptions via phone/online platforms (it is recommended to attach on-site videos or photos).
2. Diagnosis and treatment
Engineers conduct preliminary remote diagnosis, and if on-site service is required, they will arrive within 48 hours and provide a repair plan.
The entire repair process is recorded, and the replacement part codes can be traced.
3. Acceptance and Follow up
